"We hired Shilpa to design an addition and remodel to our existing house in Fremont and we had a wonderful experience working with her. She listened and understood our needs, and designed the house of our dreams in the limited area that we had. She gave us many different design options in the beginning and made many revisions as per our requests. She even helped us with the city permit process and made revisions as per city requirements. The final result turned out beautiful, she used every inch of the space and the addition looks very much part of the original house. I am enjoying my beautiful house and get complements from everyone. I am very happy that I hired Shilpa and her team for my project and would definitely recommend her to others."

"Our kitchen remodel exceeded our expectations, providing us with a beautiful and highly efficient space for cooking and gathering. We're thrilled with the results, as the new design seamlessly integrates style and functionality."

"Jessa was wonderful to work with! She explained the process in a way I could understand, was prompt with communications and I actually enjoyed it. She told me building a house might lead to building more and I can see why. It's immensely satisfying to design something and then see it come to life! We were told the drafting would be 3-5 weeks and we took every bit of 5 weeks because we really wanted to take our time in between each revision. I'm glad they didn't hurry us because as a family we did not agree on certain details quickly. Love our forever home and so glad we chose the right place for the design and drafting."

"Response excellent good job thorough"
